SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 328,563, dated October 20, 1885.

Application led June 9, 1885. Serial No. 168,125. (No model.)

To all whom it may concern: p

Beit known that l, DANIEL E. BEvERsTnIN, a citizen of the United States, residing at Middlebury, in the county of Elkhart and State of Indiana, have invented a new and useful Improvement in Window Sash Balances, of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to an improvement in window-sash balances, the object being to provide devices of this character which shall be simple in their construction, strong and durable, cheap to manufacture, and readily and easily operated.'

Vith these ends in view the invention consists in the improved construction and combinations of parts hereinafter' fully described, and pointed out in the claims.

In the drawings, Figure l is a front elevation of a window frame and sashes, showing my improved balancing devices applied thereto. Fig. 2 is a top plan. Fig. 3 is a transverse vertical section on the line w of Fig. 2. Fig. 4 is a cross-section on the line y y of Fig.- 2; and Fig. 5 is a detail view of the sheave and means for holding the cord upon the same. (Shown in Fig. 2.)

In the accompanying drawings, in which 1 ke letters of reference indicate corresponding parts in all the figures, A represents the window-frame, and B and C the upper and lower sashes thereof, which slide in guides of said frame, as usual. In the upper crosspiece, a, of the window-frame are provided openings b, into which extend headed pins c. Upon these headed pins c are mounted sheaves c', and on the pins c are located disks e, which are rigid on said pins, and which are located on the outer sides of the sheaves. Upon the headed pins c, near the inner ends of the same, are disksf, having the projecting nibs, which close the space between the disks, and thus prevent the cords from detachment from the sheaves. These inner disks, f, are held in place against the sides of the sheaves by spiral springs g, which bear against the heads of the pins c at one end and against the inner sides of the disks at their other ends. It will be seen that by providing the disk f and. locating the springs g upon the headed pins so that they will bear against the disks, all possibility of the cords becoming detached from the sheaves is prevented by the nibs of said disks.

Secured to the sides of the lower sash, near the upper end thereof, are cords D, which pass up and over the sheaves c', and then down to the upper sash.

Upon the sides of the upper sash, a short distance from the upper end thereof, are secured brackets E, in which are journaled sheaves G, over which the cords D are adapted to pass. In the sides of the frame A, at the upper front side thereof, are provided recesses j, in which are fitted brackets k. In the brackets 7c are journaled sheaves Z, over which the cords D are adapted to pass, and attached to the lower or free ends of said cords D are weights X.

The operation is as follows: The upper sash may be lowered a distance or space equal to the length of the cords that extend beyond the sides of the frame, before the lower 4sash will be affected by the movement of the upper Sash. As soon, however, as the weights come to the recesses in the sides of the frame, the lower sash is raised by the cords. By holding the upper sash in place the lower sash may be raised independent of the same.

The sashes may be raised and lowered and held balanced at any desired adjustment by raising or lowering the lower sash.

l Having fully described my invention, I claim-- 1. The window-frame A, having sheaves or pulleys c at its top and sheaves or pulleys Z at its sides, in combination with the upper and lower sashes, sheaves G, fitted in the upper sash, and cords connected to the lower sash, then passing up over the sheaves C', thence down and around the sheaves G, and finally up and over the sheaves l, weights being secured to the ends of the cords, for the purpose set forth.

2. The frame, in combination with the pin, the sheave or pulley mounted thereon, and a pair of disks located on the pin and forming an inclosing shell or case for the sheave or pulley, one of the disks being movable and held normally against the pulley by means substantially described, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

DANIEL E. BEVERSTEIN.
